=head1 NAME |
95 |
|
|
|
96 |
|
|
Convert::UUlib - Perl interface to the uulib library (a.k.a. uudeview/uuenview). |
97 |
|
|
|
98 |
|
|
=head1 SYNOPSIS |
99 |
|
|
|
100 |
|

=head1 DESCRIPTION |
103 |
|
|
|
104 |
|
|
Read the file uulibdoc.dvi.gz and the example-decoder source. Sorry - more |
105 |
|
|
to come once people use me ;) |
106 |
|
|
|
107 |
|
|
=head1 SMALL EXAMPLE DECODER |
108 |
|
|
|
109 |
|
|
The following code excerpt is a minimal decoder program. It reads all |
110 |
|
|
files given on the commandline and decodes any files in it. |
111 |
|
|
|
112 |
|
|
use Convert::UUlib ':all'; |
113 |
|
|
|
114 |

|

115 |
|
|
|
116 |
|
|
for($i=0; $uu=GetFileListItem($i); $i++) { |
117 |
|
|
$uu->decode if $uu->state & FILE_OK; |
118 |
|
|
} |

=head1 Exported functions |

|
|
235 |
|
|
Initializing and cleanup (Initialize is automatically called when the |
236 |
|
|
module is loaded and allocates quite a bit of memory. CleanUp releases |
237 |
|
|
that again). |
238 |
|
|
|
239 |
|
|
Initialize; # not normally necessary |
240 |
|
|
CleanUp; # could be called at the end to release memory |
241 |
|
|
|
242 |
|
|
Setting and querying options: |
243 |
|
|
|
244 |
|
|
$option = GetOption OPT_xxx; |
245 |
|
|
SetOption OPT_xxx, opt-value; |
246 |
|
|
|
247 |
|
|
Error and action values => stringified: |
248 |
|
|
|
249 |
|
|
$msg = straction ACT_xxx; |
250 |
|
|
$msg = strerror RET_xxx; |
251 |
|
|
|
252 |
|
|
Setting various callbacks: |
253 |
|
|
|
254 |
|
|
SetMsgCallback [callback-function]; |
255 |
|
|
SetBusyCallback [callback-function]; |
256 |
|
|
SetFileCallback [callback-function]; |
257 |
|
|
SetFNameFilter [callback-function]; |
258 |
|
|
|
259 |
|
|
Call the currently selected FNameFilter: |
260 |
|
|
|
261 |
|
|
$file = FNameFilter $file; |
262 |
|
|
|
263 |
|
|
Loading sourcefiles, optionally fuzzy merge and start decoding: |
264 |
|
|
|
265 |
|
|
($retval, $count) = LoadFile $fname, [$id, [$delflag]]; |
266 |
|
|
$retval = Smerge $pass; |
267 |
|
|
$item = GetFileListItem $item_number; |
268 |
|
|
|
269 |
|
|
The procedural interface is undocumented, use the following methods instead: |
270 |
|
|
|
271 |
|
|
$retval = $item->rename($newname); |
272 |
|
|
$retval = $item->decode_temp; |
273 |
|
|
$retval = $item->remove_temp; |
274 |
|
|
$retval = $item->decode([$target_path]); |
275 |
|
|
$retval = $item->info(callback-function); |
276 |
|
|
|
277 |
|
|
Querying (and setting) item attributes: |
278 |
|
|
|
279 |
|
|
$state = $item->state; |
280 |
|
|
$mode = $item->mode([newmode]); |
281 |
|
|
$uudet = $item->uudet; |
282 |
|
|
$size = $item->size; |
283 |
|
|
$filename = $item->filename([newfilename}); |
284 |
|
|
$subfname = $item->subfname; |
285 |
|
|
$mimeid = $item->mimeid; |
286 |
|
|
$mimetype = $item->mimetype; |
287 |
|
|
$binfile = $item->binfile; |
288 |
|
|
|
289 |
|
|
Totally undocumented and unsupported(!): |
290 |
|
|
|
291 |
|
|
$parts = $item->parts; |
292 |
|
|
|
